Renowned and without doubt unrivalled to this day, is the contribution of the ancient Greeks to the field of Philosophy and the Fine Arts. Likewise familiar is their contribution to the field of Science. However, the technology of the ancient Greeks is relatively unknown, just as is their incredible performance in this field. The present exhibition of ancient Greek technology includes approximately 300 operating models of ancient Greek inventions. The ancient Greek technological marvel (from the robot – servant of Philon to the cinema of Heron and from the automatic clock of Ktesibios to the analog computer of Antikythera) covers the period from 2000 BC until the end of the ancient Greek world. All were constructed by Kostas Kotsanas, through 22 years of extensive research and study. It is the most credible (since it is based solely on the thorough study of the ancient Greek, Latin and Arabic literature, vase painting information and minimal relevant archeological finds) and the most comprehensive exhibition of its kind worldwide. All the exhibits and their supporting material have been created by the creator of the museums without any subsidy from any public or private institution and are permanently housed at the homonymous Museum of Ancient Greek Technology and the Museum of Ancient Greek Musical Instruments and Toys & Games operating in Katakolo under the auspices of the Municipality of Pyrgos, Greece.
